Soft, pillowy, and dotted with melty dark chocolate, these Banana Bars are the kind of treat that disappears off the counter before they've even had a chance to cool. I started making them on a whim one afternoon when I had a bunch of spotty bananas sitting there giving me the look, and I didn't want another loaf of banana bread. The batter comes together in one bowl, and the whole thing bakes in under 20 minutes.
If you love my Pumpkin Chocolate Chip Bread or the fudgy richness of Roasted Chocolate Cherry Brownies, these bars are going to feel like a natural fit in your kitchen. And if you're in more of a creamy-dreamy mood, my Raspberry Cheesecake is always waiting.
Why You'll Love This Banana Bars
These banana bars come together in one bowl with no mixer, no fuss, and ingredients you probably already have on hand. The batter takes about 10 minutes to mix, slides into the oven, and bakes up soft, moist, and golden in under 20 minutes. If you've ever made banana brownies or banana blondies, this feels just as easy but even quicker to pull off on a busy weekday.

Banana Bars Ingredients
Here's a quick look at what goes into these banana bars and why each ingredient matters.
See Recipe Card Below This Post For Ingredient Quantities
- Ripe banana : This is the base and the main sweetener. The riper and spottier the bananas, the sweeter and more flavorful your bars will be. Measure out exactly 1 cup once mashed.
- Coconut sugar : Adds a soft, caramel-like sweetness without spiking things too high. It pairs beautifully with banana and chocolate.
- Unsalted butter, melted and cooled : Gives the bars moisture and richness. Let it cool to room temperature before mixing so it doesn't cook the egg.
- Unsweetened almond milk, or milk of choice : Thins the batter slightly and adds a little moisture. Any milk works fine here.
- Large egg : Binds everything together and helps the bars set up with a tender crumb.
- Pure vanilla extract : Rounds out the flavor and makes the whole thing smell like something from a bakery.
- White whole wheat flour : Gives the bars structure while keeping them soft. It's a whole grain flour with a milder taste than traditional whole wheat.
- Baking soda : Helps the bars rise and stay light and fluffy, not dense.
- Ground cinnamon : Adds a subtle warmth that plays perfectly with the banana flavor.
- Ground nutmeg : A tiny pinch goes a long way. It adds depth and that cozy bakery aroma.
- Kosher salt : Balances all the sweetness and makes every other flavor pop.
- Dark or semi-sweet chocolate chips, divided : The ⅓ cup folds into the batter for gooey pockets of chocolate throughout. The extra 2 tablespoons go on top so every bar has melty chocolate on the surface.
How to Make Banana Bars
A one-line note: stir gently and don't overmix once the flour goes in.
Prepare the pan: Place a rack in the center of your oven and preheat to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, letting it hang over two sides so you can lift the bars out easily. Give it a light coat of nonstick spray.
Mix the wet ingredients: In a mixing bowl, mash your bananas until smooth and confirm you have exactly 1 cup. Add the coconut sugar, melted and cooled butter, almond milk, egg, and vanilla extract. Stir everything together until well combined.
Combine the dry ingredients: In a separate bowl, stir together the white whole wheat flour, baking soda, cinnamon, nutmeg, and kosher salt until mixed.
Make the batter: Pour the dry ingredients into the wet ingredients. Stir with a wooden spoon or spatula just until the flour disappears, no more. Fold in the ⅓ cup of chocolate chips.
Fill the pan: Scrape the batter into your prepared pan and smooth the top into an even layer. Scatter the remaining 2 tablespoons of chocolate chips evenly over the surface.
Bake: Slide the pan into the oven and bake for 16 to 20 minutes. Start checking at 16 minutes. A toothpick poked into the center should come out clean with only a few moist crumbs attached.
Cool and slice: Set the pan on a wire rack and let the bars cool completely before cutting. Use the parchment overhang to lift them out, transfer to a cutting board, and slice into 16 squares.
Substitutions and Swaps
To make dairy-free: Use almond milk or coconut milk, and swap the butter for an equal amount of vegan butter or melted coconut oil.
To make vegan: Follow the dairy-free swaps above. For the egg, try a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, rested for 5 minutes).
To make gluten-free: Replace the white whole wheat flour with an equal amount of a 1:1 gluten-free all-purpose baking flour blend.
No coconut sugar? Regular brown sugar works as a swap in the same amount.
Chocolate chip options: Dark chocolate chips give a richer, slightly bittersweet bite. Semi-sweet is a little milder and sweeter. Both work beautifully.

Storage Tips
At room temperature: Store the bars in an airtight container for up to 3 days.
In the refrigerator: They'll keep for 5 to 7 days. Let them come to room temperature before serving, or give them a quick 10-second warm-up in the microwave.
To freeze: Wrap individual Banana Bars in plastic wrap, place in a zip-top freezer bag, and freeze for up to 2 months. Thaw at room temperature or warm gently in the microwave.
Expert Tips
Use very ripe bananas. I'm talking deeply spotted, almost all brown. They're sweeter, softer, and mash into the batter like a dream. Under-ripe bananas just don't have that deep banana flavor.
Don't overmix. Once you add the dry ingredients, stir only until the flour disappears. Overmixing develops gluten and leads to tough, dense bars instead of soft and tender ones.
Cool completely before slicing. I know it's hard to wait, but cutting warm Banana Bars makes them fall apart. Let them sit on the rack until fully cooled, then slice cleanly.
Check early. Oven temperatures vary. Start testing at 16 minutes. You want moist crumbs on the toothpick, not wet batter, and definitely not a totally dry toothpick, which can mean overbaked.
Measure your banana. The recipe calls for exactly 1 cup of mashed banana. Three medium bananas usually gets you there, but it's worth checking. Too much banana and the bars get dense; too little and they lose moisture and sweetness.
FAQ
Can I make banana bars with overripe bananas?
Yes, and overripe is actually preferred. The spottier and softer the bananas, the sweeter and more flavorful your bars will be. This is a great recipe for bananas that are too far gone for snacking. My tip: freeze overripe bananas and pull them out whenever the craving hits.
How do I keep banana bars moist?
A few things help. First, use ripe bananas, which have more natural sugar and moisture. Second, don't overbake. Pull the bars out as soon as the toothpick comes back with just a few moist crumbs. Third, store them in an airtight container right away. If you're refrigerating them, a quick microwave warm-up before eating brings that soft texture right back.
What type of chocolate chips work best in banana bars?
Dark chocolate chips are my personal pick because they balance the natural sweetness of the banana without making things too sugary. Semi-sweet chips are a great option if you want something a little milder. Mini chocolate chips also work well and spread more evenly through the batter, so you get chocolate in every single bite.
Are banana bars healthier than banana bread?
These Banana Bars are a bit lighter than traditional banana bread. They use coconut sugar instead of refined white sugar, white whole wheat flour instead of all-purpose, and a smaller amount of butter. They come in at around 98 calories per bar, which makes them a pretty reasonable healthy sweet snack or lunchbox treat compared to a full slice of banana bread. That said, both have their place in life.
